I haven't written there any news for a long time, so I would like to show you some of our new and the newest models.

For those how hasn't visited our site for a long time (I hope there is nobody like this ), have a look at our 1/87 dioramas. We released 7 dioramas with tanks from various wars and campaigns. Buildings paper models | Bestpapermodels.com
